Mucocele is a mucus-containing benign lesion, whose clinical characteristic of slow expansion may lead to ero- sion and remodeling of the bony sinus walls. When the internal content of the mucocele becomes infected, the le- sion is called mucopyocele. The etiology of mucocele formation is multifactorial including inflammation, allergy, trauma, anatomical abnormality, previous surgery, fibrous dysplasia, osteoma, and ossifying fibroma. During the past decades since the introduction of endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS), paranasal sinus mucoceles following ESS have been increasingly reported. However, giant mucopyoceles of the frontal sinus expanding cerebral parenchyma are extremely rare. In this case report, we describe a case of huge frontal sinus mucopyocele compressing left frontal lobe after ESS, which was successfully treated by wide marsupial- ization via the transnasal endoscopic approach.

Sudden sensorineural hearing loss (SSNHL) is defined as acute hearing loss of >30 dB at threeconsecutive frequencies, with an abrupt onset (within 3 days). In most patients with SSNHL,an exact cause is rarely identified. Diverse etiological theories have been proposed, includingvascular disease, viral infection, autoimmune disease, inner ear hydrops, and genetic factors. Based on these hypotheses, various treatments have been tried, including corticosteroids (sys-temic and/or intratympanic), antivirals, vasoactive drugs, and hyperbaric oxygen therapy(HBOT), but the evidence remains inconclusive. The 2019 American Academy of Otolaryn-gology-Head and Neck Surgery guideline had suggested that HBOT can be provided as eitherinitial or salvage treatment when combined with steroid therapy. HBOT, a noninvasive treat-ment involving the inhalation of 100% oxygen at a pressure of >1 atmosphere absolute (ATA)is another treatment option as a method to improve oxygen supply after cochlear damage. Al-though the pressure, frequency, and total time of HBOT remain variable among differentstudies, a protocol of 2.0-2.5 ATA and 10-20 sessions in total are commonly used. The treat-ment strategies for SSNHL have been evolving, and recent attempts involved increasing theeffectiveness through various combinations of systemic steroid, intratympanic steroid, andHBOT. In this review, we will review various studies about HBOT and discuss the efficacy of HBOT in SSNHL.

Background and Objectives: Blood neutrophil-to-lymphocyte ratio (NLR) has been reported to have poor prognostic impact in variable malignancies. However, studies evaluating the clinical significance of blood NLR in patient with papillary thyroid carcinoma (PTC) has been relatively rare, and the outcomes were inconsistent. In this study, we sought to analyze the clinical value of NLR in patients with PTC who had cervical lymph node metastasis. Materials and Methods: Retrospective chart review was conducted with 174 patients with confirmed neck metastasis of PTC after initial thyroidectomy. Blood NLR was estimated by dividing the absolute number of blood neutrophil with that of lymphocyte. Statistical analysis was conducted to evaluate correlation between NLR and clinicopathologic factors, patterns of metastatic lymph nodes, and recurrence. Results: Higher NLR (>1.74) was correlated to younger age of patients (<45 years, p=0.045) and smaller size of tumor (<1 cm, p=0.017). Blood NLR had no impact on patterns of lymph node metastasis or recurrence. Conclusion: Blood NLR may not be considered as a predictive factor for clinical aggressiveness or prognosis in patients with PTC with lymph node metastasis.

Patulous eustachian tube (PET ), a disorder of the eustachian tube (ET ) occurs when the ET remains open in resting state. Patients with PET may experience symptoms such as aural fullness, autophony of voice or breathing sound. It is not challenging to diagnose PET due to the characteristic symptoms, which are relieved in the recumbent position. The term “Masked PET” refers to a condition that symptoms of PET do not manifest until after middle ear surgery, as they were initially masked by conductive hearing loss. In this report, we present a patient who developed symptoms of PET after successful tympanoplasty, resulting in hearing improved. Based on this case, we suggest that all operators consider the possibility of the “masked PET” condition and explain it to the patient in advance to avoid situation of disappointment after surgery.

Funds statement found in practice today are a hodgepodge of miscellaneous information presented in a confusing and misleading way. Many accountants see the problem as one of defining "funds". They attribute the confusion over the funds statement to confusion over what is meant by the term "funds". In 1964 John b.Coughlan Observed that the funds Statement based on working capital changes has "baffled a generation of accounting students" and "it is therefore hardly conceivable that it has enlightened Stockholders and other lay readers". The solution to the problem of the funds statement does not lie in searching for a new definition of funds that will enable all of the objectives of the Statement to be achieved. It lies in identifying clearly the financial reporting objectives that need to be achieved but are not achived by the balance sheet and income Statement and designing new Statement that achieve those objectives.
